is there way configparser in python set value without having sections in config file?
if not please tell me of alternatives.
thank you.
more info: have config file format: name: value it's system file want change value given name. wondering if can done module instead of manually writing parser.
you use csv module of work of parsing file , writing out after made changes -- should relatively easy use. got idea 1 of answers similar question titled using python's configparser read file without section name.
however made number of changes, including coding work in both python 2 & 3, unhardcoding key/value delimiter (but colons default), along several optimizations.
from __future__ import print_function # module main() test function import csv import sys py3 = sys.version_info[0] > 2 def read_properties(filename, delimiter=':'): ''' reads given properties file each line of format key=value. returns dictionary containing pairs. filename -- name of file read ''' open_kwargs = {'mode': 'r', 'newline': ''} if py3 else {'mode': 'rb'} open(filename, **open_kwargs) csvfile: reader = csv.reader(csvfile, delimiter=delimiter, escapechar='\\', quoting=csv.quote_none) return {row[0]: row[1] row in reader} def write_properties(filename, dictionary, delimiter=':'): ''' writes provided dictionary in key sorted order properties file each line in format: key<delimiter>value filename -- name of file written dictionary -- dictionary containing key/value pairs. ''' open_kwargs = {'mode': 'w', 'newline': ''} if py3 else {'mode': 'wb'} open(filename, **open_kwargs) csvfile: writer = csv.writer(csvfile, delimiter=delimiter, escapechar='\\', quoting=csv.quote_none) writer.writerows(sorted(dictionary.items())) def main(): data = { 'answer': '6*7=42', 'knights': 'ni!', 'spam': 'eggs', } filename='test.properties' write_properties(filename, data) newdata = read_properties(filename) print('read in: ') print(newdata) print() open(filename, 'rb') propfile: contents = propfile.read() print('file contents: (%d bytes)' % len(contents)) print(repr(contents)) print(['failure!', 'success!'][data == newdata]) if __name__ == '__main__': main()
